One more trivial question.
With the above setup, the #6 wires from the 140 watt doghouse panels are going straight to the battery
bank (after switches and fuses).
It works out that these wires would go right past the MPPT
controller the the 320 watt davit panel feeds into.
The #4 wire from the controller goes to the battery bank.
Is there any reason why I shouldn't connect the #6 wires to the out #4 wires going from the controller to the battery bank.
It means just one pair of #4 wires going to the battery bank instead of #4 and #6 going seperately.
It just seems like a tidier arrangement.
I guess I'm asking if the #4 wires could cope.
